Agro-Waste Biochar to Reduce the Leaching of Heavy Metals from Coal Fly Ash Amended Soil

The soils added with coal fly ash may contain heavy metals potentially up to the levels of toxicity. Biochars have been successfully used in past reduce bioavailability and leaching contaminated soils. Therefore, co-application biochar together could positively change characteristics sandy through various fixing mechanisms. In present study, authors investigated effect agro-waste modifying loss from Column tests simulated rainfall conditions were conducted for Ultisol mixed avocado branch cut biomass at 5 tons/ha rate. results showed presence leachate soil. Application significantly reduced leachability all tested study. reduction rates 55% compared non-amended samples. can effective be stabilizing soils, minimize risk environmental contamination.
